Surface requirements: The concrete surface should be cleaned, repaired and polished to a certain degree of roughness. Ensure that the concrete is fully cured, the strength reaches C25 or above, and the moisture content is less than 8%. After the surface is treated, the next process should be carried out as soon as possible.
Ambient temperature and humidity requirements: The ambient temperature at the construction site should be higher than 5°C, and the relative humidity should be less than 85% before construction can be carried out.
Ventilation conditions: Ventilation should be maintained during construction.
